It flies in “pumping” cycles: the kite reels out, then a winch reels the kite back in. While the Hawk unfurls, the kite weaves to and fro in a figure-eight pattern, optimal to catch crosswinds. As the winds pull at the kite, they also pull at its tether—generating electricity on the ground.

After the tether reaches its maximum length, the ground station winches the kite back in. Though the Hawk must expend energy for reel-in, it expends only a fraction of the energy, resulting in a net energy gain that varies by wind speed. An entire cycle takes about 100 seconds: 80 for reel-out and 20 for reel-in.

I did not see that coming. I thought it would have turbines attached to the kite, the kite being simply a way to get the turbines higher up to faster, more consistent wind.
